Hello All!
Thanks for adding me to the forum!
I have to replace the 3/32 fuel line that I believe is the primer line to the crank case. There is one nipple below the fuel pump and then 6 nipples running down the side of the case. I have the schematic which I will attach below but it is not helping me out with how I route the fuel line. I have the lower section of hose which Ts off to the lower nipple on the case and then upwards but the way the upper five are connected from then on is a mystery to me. The line has been melted as there was a serious overheat.
Will attach model number and pics below.
Any help much appreciated!
Nick

Any advice or maybe some photos from someone who has this motor would be awesome! Compression is good in all three cylinders and motor fired right up 1st crank and ran smooth so am hoping the is the last fix for now after doing the water pump, impeller and thermostat.

Apparently the manual does not have a picture of how those recirculation lines go.-----Perhaps someone with photo posting experience can help.-----That is beyond my pay scale.----There is one nipple to feed fuel to the engine from the electric primer valve.

Just bumping this up again in case anyone has this motor and can help out with photos of recirc system. Currently what I think are the fuel input barbs plumbed together in series from the electric primer valve. Was told the right angle barbs are likely the oil recirc and I currently have those three capped off.
Motor will currently start from cold in the Am first crank but die after a couple of minutes and won't start the rest of the day.
On secondary note I got 138, 128 and 135 on a cold compression test with WOT. Are these numbers close enough? Within 7% based on my calculations. Some things I've read have said within 10% is normal and have also heard within 5%.
