Joys of two strokes ! Found an old post regarding timing :- points start opening 5/32 inch BTDC. Also refitting flywheel accurately.As said check simple things first although My previous workings with 2 strokes best do a leak down test to check condition seals especially old engines.

Just some more info,the engine would start okay and run for 30 mins then stop. After cooling it would start again.It has had a new set of points/condenser/coil fitted but will not start at all now. Personally i would be looking at crank seals ( 2 stroke) but the machine belongs to a work colleague.

I should have added that the model is a C25 with points set up

Pulse jet carb. To be fair I was not 100 % satisified with its running but engine is fitted to cement mixer so neglected over last 30 yrs

[rotevat]

Sorted. I had forgot to tighten the carb to cylinder head bolts so running lean.

Done some research on this.Apart from cleaning the carb through again advised to check carb to fuel tank seal and “preload” diaphragm. This is achieved by pulling out choke by app 3/8 ins and then tightening carb to tank screws ?

Not sure about two speed pulley. Standard P.T.O end one. Hopefully my attempts for a weld repair will be okay. Have not found a uk supplier of pulleys yet.

Fitted to cement mixer. 3 hp engine 1982 built date. Engine is black painted. Have someone Who has offered to weld it so fingers crossed.

After some searching the bore on my engine is alloy not steel. Therefore honing not recommended. Standard rings to fit then

[rotevat]

Is it still necessary to hone bore if fitting standard rings. When I turn crank the piston Drags up oil onto the bore wall. I presume the oil scrapper ring is u/s ?

My account shows trial membership till Dec21 which must be a fault. Also I can still post on forums ? Have tried to upgrade to paid membership but but will not accept current un & password as already logged. Bit stuck at moment

[rotevat]

I think its an issue with my membership.
Im on a 12 month trial membership which excludes me from membership content (can still post in forums) but then i can not upgrade to full membership either ? I have sent a “help” message to admin.

[rotevat]

Cheers for the info. Struggling a bit with the PM thing ?
