Thanks Robert , I have seen and looked into those , same model as I picked up today.

Andy.

Both should improve running.

Andy.

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

Andy.

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

Andy.

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

Andy.

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…[Read more]

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.

Andy

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.

Geoff , very tue words , as well as the internet provides us with good info , it also carries some bloomers. The recent thread on here a…[Read more]

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.

Andy.

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

Andy

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…[Read more]

Acme
Corborn (spelling???)

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

Andy.

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

Andy.

You’re right Angus , I’ve seen the Hayter 21/osprey with the JLO engine.

Andy.

Yes , from memory they are Bosch components

You gents are spot on , it’s a JLO engine , and it DOESN’T have a diaphragm carb , JLO normally sourced their carbs from Bing , plenty of parts for these are available on the continent.
