Title: Help on the Flapster Post by: gazzagood on May 14, 2014, 06:19:54 PM Hi as you all know I got the Flapster the other day
But having bit trouble with ticking over only works with the choke quarter pulled out so revving too high won't tick over if push choke in. If I remember dizzy had the same problem when he brought it I'm wondering if he ever fixed this problem. Any help much appreciated Gaz Title: Re: Help on the Flapster Post by: Olds on May 14, 2014, 07:17:19 PM Sounds like the jet height needs setting if it's still running a SU carb.
Title: Re: Help on the Flapster Post by: gazzagood on May 14, 2014, 07:35:12 PM Yes still on su carb
Title: Re: Help on the Flapster Post by: gazzagood on May 14, 2014, 07:36:59 PM Please tell me more. Olds
Title: Re: Help on the Flapster Post by: Olds on May 14, 2014, 07:49:51 PM Best bet is to read fifers excellent set up description.
https://sites.google.com/site/fifersrelianthintsandtips/carb-stuff/carb-maintenance/carb-only-runs-with-the-choke-out Easier than me trying to write it down again. Title: Re: Help on the Flapster Post by: fifer on May 14, 2014, 07:54:32 PM Get it running and fully warmed up .
Turn the throttle screw clockwise to raise the tickover and push the choke cable fully in . The engine should now be running at a fast tickover . Check the gap between the choke lever screw and the throttle lever ; it should be about 40 thou . Get a magic marker and mark one flat on the big nut under the carb . Turn the big adjuster nut clockwise { downwards } a flat at a time till the engine speeds up and is running its fastest . Drop the tickover down and recheck the gap on the choke screw . Adjust gap to 40 thou and that is where your cold starting setup should be correct . . .

Title: Re: Help on the Flapster Post by: gazzagood on May 15, 2014, 09:00:51 PM We'll it passed mot it's got 12months tax on so ready to go. But this problem with tick over still a problem spent 5hours on setting carb up to fifers very kind help. But it now running without choke but it now hunting. Ie ticking over then the revs go up and down its not a steady tick over could the needle be warn
Title: Re: Help on the Flapster Post by: spanners on May 15, 2014, 09:03:59 PM sounds like an air /vaccum leak on the carb or manifold,, also check the vac pipe to the dizzy or the advance unit on the dizzy.
Title: Re: Help on the Flapster Post by: gazzagood on May 15, 2014, 09:11:27 PM Oh and the oil pressure light going out but when it revs up high the oil light comes on but the oil level correct
Title: Re: Help on the Flapster Post by: gazzagood on May 15, 2014, 09:13:06 PM And thanks spanners
Title: Re: Help on the Flapster Post by: Olds on May 15, 2014, 09:52:48 PM But it now running without choke but it now hunting. Ie ticking over then the revs go up and down its not a steady tick over could the needle be warn Could also be worn throttle spindle/carb body. Lowering the jet a few more flats will make it run a little richer (safer than too lean) and may help.I assume you have checked there is oil in the damper chamber. No idea as to the oil light. Might be a good idea to check the pressure. Glad to hear the MOT was OK and it's back on the road. Title: Re: Help on the Flapster Post by: fifer on May 15, 2014, 10:04:50 PM Check as per spanners recommendations and also Old Newbie recommendations .
As for the oil light , if all the terminals are connected correctly and the fault is still there , it is common practice is to replace the oil light switch and see if that helps first before looking at the oil pressure relief valve . . . Title: Re: Help on the Flapster Post by: Manky Monkey on May 16, 2014, 08:25:01 AM Hiya, I built the Flapster many moons ago now. At the time Flap, (Darren), & I worked together at Royal Mail. He was into off-roading & had a canvas roofed LandRover, which his kids nicknamed Flap. We shared an interest in mechanical tinkering so he took me to an off-roading event in Oxford. In return, I took him to Poole bike night on my trike. He was instantly hooked & had to have one. We built it in his aunt's garage, with me doing the design, sourcing of parts, ( I already had a spare engine & axle), welding etc & him bending tubes, fabricating brackets n stuff. We had several parts collecting trips -the front end came from the Netley Marsh autojumble & we picked up the rear wheels & tyres at the Beaulieu jumble. We had to roll 'em the whole length of the Beaulieu estate back to his car. He wanted something vaguely 70s muscle car ish while I fancied building it "chubby", with everything deliberately over sized, like a big kid's toy, (which is what it was). I remember he was concerned about the stresses on the headstock, so there's some big chunky welds around it that I always wanted to smooth out.
My trike had a rear mounted radiator with the water running through the frame tubes, which worked fine, but I'd already decided I wanted a very simple little single seater next. So I built his frame more or less the way I envisaged my next one. By the time we'd finished his, I'd taken mine off the road & stripped it down to build the next one though, so we never got to ride together. I've spent 35 years tinkering with motors, but I'm no mechanic. I took my own trike to a local tuning guy, near Winchester: http://aireytuning.com/ an ex grass track racer with a rolling road in a shed behind his house. In half an hour he transformed the performance of my engine with nothing more than a bit of filing of the carb needle & a few tweaks with a screw driver. In my own very humble opinion though, my first check would be the oil level in the damper, (the large screw cap on the top of the carb). Darren won a "QuickBob" fuel tank for a quid in a raffle when we went to the NCC Diamond Day show at the Ace Café on my trike, but because it's so wide, we had to make an extended carb inlet. It ran with no problems at all, but occasionally iced up on long runs, so he wrapped it in exhaust bandage, which cured it. If I remember right, he ran it slightly rich to offset any fuel evaporation in the inlet tube. I also agree with the chaps -bung a new oil light switch in first. They don't last forever & it doesn't take a lot to gunge 'em up. A good service, fresh oil, new plugs & give it a bit of a run -that's probably all it needs. Great to know it's still out there & being enjoyed, not rotting away in a garden somewhere. Piccies please! http://www.mankymonkeymotors.co.uk/Trikespageimages/flapster/trike.html Title: Re: Help on the Flapster Post by: kapri on May 16, 2014, 11:18:28 AM I've used Tom Airey for tuning several times, he's excellent.
Title: Re: Help on the Flapster Post by: gazzagood on May 16, 2014, 06:21:03 PM We'll she lives again took me all day today to get the card striped Down and reassembled still wouldn't run right so had spare carb in shed stuck that on 10 min job she purs like
Even the carb sorted the oil problem unbelievable init. Gaz Title: Re: Help on the Flapster Post by: twisted on May 16, 2014, 07:32:16 PM well done sir ;) now get out and put a few more miles on it ;D
