the 350 Holley is just too big for the 186, you need to muck around a fair bit to get them working right - changing jets and power valves - and your landy will drink fuel like nobody's business. If you were going to have a massive cam and some head-work done then maybe, but there are better options.
The main reason why lots of people go with the Holley is because they are pretty cheap and parts are easy to get. They are also easy to tune and dont give much trouble.
The webber is a great choice for the 186 - your best bet is to get it rebuilt and jetted correctly by a carby guru. You'll get great power and pretty decent economy.
The dunny box stromy is OK, but not very efficient. Jetting and careful tuning can give pretty good results but the 2 barrel version from the 186s is a better option. The problem with this is getting your linkages to match up - although same problem exists with the holley (cable operated).
All in all, unless you have a performance cam and/or other performance mods I would stick with the webber you have. The Holley is great if you have a worked over donk, but crap on a stock one.
performance isn't what i'm after - i thought the weber may be too small as it is listed as being suitable for engines 'up to 2 litre'.
I'll wipe the holley off the list, then. the one I have someone has removed the choke butterflies.. and it is a total pain to start when cold.. do you think refitting the chokes will help that ?
Yeah mate, refitting the chokes is a good idea and will improve the drive-ability when cold. The weber will be great but you may need to up the jet sizes a bit. Best bet is to get it refurbished by a carby shop then have them tune it.
Just thinking though, sometimes people grind off the choke fittings when they remove them - hopefully you are not in this position.
I have been reading the threads about Strombergs on the Landy motors over the last couple of weeks, so thought I would pay some attention to olmate (been preoccupied with the series 1 for a while). The Stromberg that was on her was off a 202 and the thing has been using a heap of juice for a while, running on and been a bugger to tune. I had fixed the running on with a solenoid but she was always rich (even with an adjustable main jet)
Got a rebuilt Stromy from Melbourne (off a 161) and now she is the best she has ever been. Done the up and down hill thing as well - without a problem. Runs smoother and quieter; even sounds better out the back
Haven't put an adjustable main jet on her as yet - might just leave her alone now as she is good enough
The standard Stromberg from a 186 as fitted to the HD, HR, HK-T-G's will be the best if you have a single throat intake manifold, they will be the simplist to service and tune, but, pay careful attention to the condition of the throttle butterfly shaft wear if buyng one second hand for economy you can jet to 161 or 179 specs.
