Hi Doug, bit of a guess with the primer caps they do vary a bit. I got a hundred new caps but quite often I see if I can use the old cap, some work, some don't and even with a new primer cap and needle, my failure rate is about 10%. This is a lot better than the failure rate I was having with the plastic needles which was about 90%.. There is no silver bullet with these but you will get it sorted and then you have one of the best machines ever made. If you end up modifying the carby as per the instructions the starting should be one/two pulls. I fitted one of these carbs last week to a 24 that still had a full crank with a G3 carb fitted, took about 15 mins because I knew it was coming and I had everything ready to go.He rang me yesterday saying it now had so much more power but at idle it was revving fast. It was easy to explain, just bend down and turn the screw on the end of the carb anti clockwise while it was running to get it to the revs he was happy with. If it moves again put a bit of silicone on it to stop it turning.He rang back a few mins later and it sounded like he had mastered something way beyond his capabilities, amazed something could be that simple. I used to always put a bit of silicone on the thread but I got a bit slack with them recently because I have been doing so many of them. I made up another 20 of those caps last night, not long since I made up the last 20
