Hi JO, and others,
Let me start from the end. Pig is a big laugh to all of us, so cute.
I was on a meeting yesterday with a friend l meet a day before, and he looks like he knows his job. He is a precise metal worker. He has offered to make me parts for my rebak with best quality materials. We discused it over a glass of wine late in the night and we found some interasting ideas, all will be reported as soon as paper transforms to metal.
Now, the for the part that more or less ruined my day.
I was seeing poor performance last few days, so l decided it was time to take a look in the filter. It was dirthy, so l cleaned it and the gasifier/cyclone as well westerday, and drove for a test today. No change! So, l swiched to pure petrol but the power was still poor.
The first thing l thod about was intake manifold with the intake air tooning walve in it got plugged with soot to a point it restricted the flow too much. Afterall, l have never cleaned it at all since l woodgased it.
I dissasembled the throtebody and saw a thick sootcake in the manifold.
The first plan was to dissassemble the intake manifold to clean it well, but this prooved impossible becouse 3 screws are only accesible if the engine in dismounted.
I put things back the way they were, started the engine, all went well then the engine stoped in idle. I was seeing a unusual smoke/steam from the valve cover vent hose too (usualy goeing in the intake manifold). It wuldnt start after that. Sparkplugs ok, nice sprk, but no run. Push started it, lots of steam trugh the engine vent. Drove for a few miles, it seemed to run well.
So, l decided to try the boiling water method. Boy, its a rough medicine! The tailpipe smokeing, the engine suffocateing, the steam rushing trugh valve cover vent. Not preety at all. But the performance got better on petrol. Just the engine vent is still spitting out steam and occasional oil.
Now, this concerns me a lot. This steamy pressure relif with loss of power in my oppinion indicates pistons not sealing well. Allso, the point things got worse when l started to sloly pour boiling water in contribute to the theory.
So, if anyone has a idea on te situalion l will we forever gratefull. Its sort of a SOS situation...
