Its a Lister LT1.
AFAIK, it produces 7.5hp @ 3,000 rpm continuous (8.3hp intermittent)
its a 408cc single cylinder air cooled DI diesel with compression ratio of 16.4:1
Got it as it had absolutely no compression.
Took the engine apart, as I wanted to check the piston rings.
They turned out OK (worn, but work)
Then my attention turned to the valves.
The exhaust valve wasn't sealing at all.
Took both valves out and reground them in, and yippee, compression
.Put it all back together, put a drop of oil in the start assist plunger, and cranked it over...
And was gladly rewarded with a nice blue puff of smoke and a pop
So pipe up a fuel tank, and it runs (loud though as the exhaust manifold piece is broken, so basically its a very short exhaust
Will solve that though.
Will run it a bit more (with the proper/better tank, read my question below)
Might need to get new rings and gasket set for it.
Reason being, is when you crank it over, with the decompressor engaged, I have to flick it off and then put some strength behind the swing and turn it through a compression stroke with no decompression...
Good thing I am a big strong lad
I want to ask a question though.
The standard fuel line for the engine is generic, fit ride on mowers, motorbikes, etc...
The only fuel tank I had to hand was a small one of an old JAP strimmer engine, which the fuel output stub is considerably smaller.
I had to use a short length of 6mm (I think) airline on the stub and then push that into the fuel tubing for the diesel.
The engine backfired most of the time it was running.
Do you think its down to the smaller pipe not flowing enough fuel?
I havent ever had to down size pipe before, its just I need to really clean out the standard tank
Once I have managed to clean out the old tank (its got leaves in it!!!), I will fit that and run the engine again.
If its all ok, and runs smoothly, I will play around with a few bits on it (Its an internal plunger fuel pump with a simple stop/on/start lever), but there is a what appears to be an engine speed adjustment lever (its a fixed speed engine), so I will wind the adjuster screws out and then see if it works as a throttle (it should).
If I can have a basic throttle setup, I will fit new pushrod seals, new base and head and rocker cover gaskets, and new piston rings to give the engine a new leash of life.
Then it will go in a motorbike
Currently its temporarily mounted to the front of an old ride on mower
(Its all I had to quickly bolt it too something )
