Get onto the Frequently asked Questions page of the web-site (british seagull FAQ's) Scroll down until you see> How do i start my british seagull. The lads have done all the homework on how to start one the proper way. If your motor is on an angle you can loosen the carb clamp bolt and twist carby untill its level to the eye. But you should do it by mounting it level in a tub of water. Have a look at the pic to see how your motor should sit and how much the water level should be at.
This is just a guide that should get you started. Lets us know how you go.

I take it by "leaning away from the carb opening" you mean leaning sideways a little not forwards or backwards, which is what could be compensated for by twisting the carb?

you say leaning by 4m ?? You mean 4mm I guess but measured how/ where. Presumably not over the entire shaft length ... you mean just across the mounting bracket. Whichever neither here nor there i would think.

It is a Villiers carb ???

Did you clean the small fuel filter on the inlet to it ?

Carb needle correctly set.
Carb centrepiece correctly fitted with the retaining screw in the slot in the shoulder, not in the round hole ??

Float height correct ?

When you attempted to start it did yo press the flooding bottom until fuel flooded out.

FWIW my Featherweight will start no matter how deeply it is immersed. With my weight in the back of the dinghy the water is not far short of the top of the transom!

I take it the plug is good or new, clean and correctly gapped. The HT lead and the plug cap are in good condition? Have you checked, cleaned and correctly set the points?

Have you checked that you have a good strong spark


I find flooding the carb, choke fully in and say half throttle ( but not critical ) is the right combination for starting .

hi sorry yes mm and yes i ment the bracket
flat set correct ???? how is this done
i usually flood it till a wee bit fuel comes out the wee hole plenty of spark new spark plug.

villers carb have not checket the carb needle yet i had it started again in the shed but when i put it in the water nothing it would turn over but not stay running ????

fuel is spot on 25/1

When you start it in the water give it full throttle and full choke. Take the prop to. Once it fires into life very quickly turn the throttle back before it overevs to the moon. Im thinking it might have a leaking head gasket and its lost a bit of compression.

Remove the tank and cyl head. What you can do is have a look at the gasket and give it a good clean (you could run a bit of sand paper over the gasket and rub until theres clean copper or whatever metal it is) Clean out the water gallerys around the cyl and wire brush the head and top of piston at TDC. You can then smear a very lite amount of silicon gasket goo on both sides of the gasket and refit it and tighten the head bolts using a toque wrench. if you dont have a torque wrench tighten the head bolts evenly and sensibly by hand. Clean and gap your plug to 20thou, and see how that goes. If it is going good then you need a new head gasket and cyl head bolts as well. This is just a trail and era to see if its the problem. See how you go.

Dont know about that one. You may need to post up a pic or two so we can see what your talking about.

Yes it looks like "you need to post a picture" time.

You will need the impeller that is designed for that engine.

Top left is what it should look like.

Take off the air intake and squirt some WD40 down the throat as you are pulling the rope. If it fires up it is probably the carb. Friendly little blighters aren't they....

[puddock]

hi yep did that and yes it tried now lost all hope for it so will be flogging it as ither spares or a one peice unit what would be a resonable price for it ???
