I had the same issue on my Spitfire. Replaced the crank seals and it runs like a champ. Those Kohlers are damn near indestructible. To get the crank seals in, you have to remove the engine, flywheel/stator, and pulley. You can replace without taking the case apart, but it takes some effort. Best to ...

I put a Mikuni VM 34 slide carb in my Spitfire (340 Kohler)... Runs great!

Yes.

Woot! Good news!

I did get a fuel line pickup for inside the tank. Don Amber from Busco Bullet will special-make one for the Spitfire. I'd definitely do that...

Ok... By any chance did you clean up the magnets on the flywheel? When I took everything off to replace the crankseals, I noted rust on the stator and flywheel... I used a dremel with a wire wheel, and very carefully cleaned off all the rust. Had a MUCH stronger spark when I did that... If you haven...

Just grasping at straws here... I noticed in your video that the fuel lines comes out of the gas tank, across the top side of the engine bay, beneath the carb to the fuel pump... The original routing of the fuel line is straight out of the gas tank, down underneath the engine (right underneath the s...

I didn't see you mention the fuel pump. The Spitfire has a vacuum actuated fuel pump. They are relatively cheap, and considering all the other replaced parts, I'd replace that too. If not, at least take it apart, clean it out, and reinstall. Also, check the hosing for splits/cracks, even a small spl...

Agree with DA. He gave the same advice to me two years ago. I tried all the 'easy' stuff, to no avail. Finally took his advice and changed out the crank seals (cleaning up the stator in the process) and now it flies! The bogging after idle is directly related to oxygen getting into engine through th...

Dropping it to $500 OBO. Adding to description above; re-upholstered seat, new fuel lines, gas tank removed & cleaned, exhaust painted black w/high-heat paint. Have about 10 hours on it since rebuild. Strong runner.

Thanks! This helps a lot!
