Both should improve running.

I could be wrong , but it sounds a shade retarded to me. VERY nice restoration.

Earlier ones imperial , later metric , measure your housing with a vernier and go from there.

It’s a Howard 400 , when up and running are a very useful and well buit machine

Wishing you a speedy and healthy recovery.

You can get away with bypassing the pump altogether , and rely on gravity feed. Removing the engine for the split couldn’t be easier , remove throttle cable , fuel pipe , and ignition kill switch wire(if it has handlebar mount) , undo bell housing bolts and it comes apart , it really is a simple operation, you should then see what could be the problem.

Rather than ponder over what at present are merely guesses ,just split it and then evaluate.Personally , I wouldn’t use thinners/acetone/vinegar , at any cost , ultrasonic cleaners are truly a great asset , and should cure the problem.
A photo of your exact engine would really help.

The clutch is more than likely the plates sticking , but hard to tell exactly until you have split it.You sound quite mechanically minded , so I’m sure you’ll identify what wrong.
The linkage issue , I would be inclined to make my own.
Fuel issue , if you nkow someone handy who has an ultrasonic cleaner , 15min cycle in one should cure the problem.

Thank goodness our hobby is vintage stuff.

“The important part of this is that you shouldn’t believe everything you read in print and you should always cross reference any facts to determine their accuracy; never rely on one source for your information.”

Geoff , very tue words , as well as the internet provides us with good info , it also carries some bloomers. The recent thread on here about Flymo engines being a good example . a clear picture of an original JLO engined machine , and a posting claiming it should have been Aspera , fortunately most of us noticed the error.

The Bux120 is fixed timing , flywheel is held in place with a cotter type pin/bolt , very similar style as a bycycle crank cotter pin.

[andyfrost]

Yes , we really need some photos , unless of course you can tell us what make of engine you have.

Andrew it’s dependant upon how we term original, would you rather have a machine with all it’s correct “original” components with perhaps what some may say has tatty paintwork , or one with pristine paintwork with a host of incorrect parts fitted.
I know which I would rather have , I’ve just purchased another Howard 700 , I bought it because it was complete , along with some original factory fitted extras , and all bits and pieces are as they should be , the paintwork is average at best , but after a few hours fettling , it did a brilliant job planting spuds this morning.

Hirth
Acme
Corborn (spelling???)
Jowett/Bradford
British Junior
Howard

I would hazard a guess the list would run into the hundreds , that’s without getting old stationary engines involved.

Thanks for that Alan , interestingly a chap in the village has a Hayterette with the Suzuki mx120 twostroke engine.
