Purchased a Alfa Laval Ronaldson Tippett 3 HP hopper cooled stationary engine in not going condition with original manual.
It had no compression so I thought probably a stuck valve.
Got it home whipped off the side cover and sure enough the exhaust valve was stuck open.
fixed that with some wd40 and machine oil.
The engine has good spark from the Lucas maggy
Turned engine over compression just not quite enough.
Put some oil down the plug with some aero start, not even a kick and compression some improvement.
Next check contact points opening, all good at 12 /100th. Still not firing up, not even a sign of combustion.
Ok check timing ,valve timing all ok, magneto was out of spec on flywheel spark indication, so off with magneto to adjust, this process reminded me of Villiers with tapered shaft.
I found the threads on the magneto attachment base almost shot so this magneto has been on and off like the proverbial .....,may have to get a plate made up, and holes for studs tapped.
Finally after two hours I had the timing just right. Fitted new spark plug.
Guess what engine still dead as a dodo and me too cranking the little mongrel. I started off with little lamb but the animals are getting bigger.
Decided to check valve clearances, both valves no gap so adjusted clearance to 016 /100th as per book.
Compression improved and I thought it would have enough to fire, but no nothing.
Pulled the carby apart and drop tube all in order there.
This has really got me scratching my head as to whats wrong.
Next step I guess is to pull the head off and check piston, rings and valve seats and gasket.
Would appreciate any advice at this stage.
One thing I was disappointed to see is the valve guides work in the middle of the water jacket and surely would let water past the guides and valve stems and into oil sump via valve clearance adjustment area. I thought the valves woud have been in tubes to protect from water.
The book does not address this issue and not showing any tubes in diagram.
What are your thoughts on this set up ?
Have included some pictures, would appreciate any feed back that in my daze may have missed before I pull the head off.
