sorry for the terminoloigy. Sometimes l have the word in mind but cant find the right expression either in my language or English
Hmm makes sence. l guess its time for a nother modofication. Plus, a full inner wall might protect the condense channel of plugging with sawdust.
Max, on the heating the wall with the 45 small nozzles l agree, much heat is lost outside. But dont forget! this is a lmbert/WK hybrid and all the lost heat is retrived back in the heart with air preheating! Atleast thats the theory. Penetration is provided with the 3 deeply protrudeing 8mm nozzles.
Do you think the downblasting or sideblasting nozzles might damage the insulating ashcone? In a normal stright nozzle configuration, the airblast jets colide in the center and travel down. In a down or spiral feding configuration there is a bigger chance of a jet to travel to the opposite side of the firetube, disturbeing the protecting ash and puting heat where it is not wanted. Just a thod.
Anyway, performed two tests today. l wanted to know what the the difference a hayfilter means. Huge!!
First, l drove without the hayfilter. Neaded to make some modifications to it so while it was off decided to try it out. Just direct cooler to engine gas suply. OK power, but terible idle and driveoff. Much hasitation while changeing throtle position.
Then, l remounted the hay filter barrel. What a difference! Better power, driveoff without hasitation, a much smoother ride. L wanted to film the nice idle and driveoff but l run out of camera memory and ended with a short video showing... well.. not much
Perhaps it at least warms up my Northern friends, we have sunny warm 24C these days.
