Thanks mate

I don't know what the fuel enrichment and plungers are lol I have never seen them, but it's probably what the problem is because I can't find anything else.

Work is a completely different thing.... I was working in community services and I spoke up about stuff that was wrong, and for my good deed I am shown the door. That's fine, is rather do the right thing than to go with the flow, but my confidence has taken a pretty big hit, and this mongrel car isn't helping lol

Update!!

I just finished rebuilding my 40mm Webers and installed them. I start turning the motor over and it starts, but then the left carb starts flooding big time! So I take the top off and replace the needle and seat.

I give it another go, and it starts, and even at the initial settings, it's already running so much better! I get it warmed up, and set the idle mixture, and it's running beautiful! It was getting late so I've called it a day. Tomorrow I'll do the final adjustments.

Thank you to everyone who have shared their advice and support!!! I have really appreciated it!!!

It's the choke assemblies, typically the cover is taken off and a blank off plate is attached. The pistons in the body stay there but if they move they will richen up the mixture causing flooding and black smoke

I checked them just before I fired it up the first time, but I think I'll be checking them again

What oil do you use in WA?

Depends if I built the engine or not, typically a 15w40, for street engines, 5w30 for higher performance closer tolerance engines. I always recommend keeping an eye on new engine oil pressures and choose the weight accordingly

15w40 semi-synthetic is what I'm using at the moment. I just installed a new 26 mm pump and blew a Ryco filter!

I've ran 20w60 Penrite some time ago in the motor and had no issues, so I doubt it's the oil, though the old pump was in pretty poor condition.

On a positive, I've almost finished connecting up my DIY Oil Catch Can!

I made it using PVC downpipe. For the hoses I used the stainless steel ones that they use under kitchen sinks. They handle high water pressure so they should cope with a little oil vapour!

I have a line coming from each tappet cover, and I'm going to connect a third line to where the fuel pump used to be. I still have to get a suitable connector. The catch can then runs to the top of each air filter.Image
